I am trying to figure out how to set 'buffers' or something of the sort on my
matplotlib plots, so that my first and last data points are not centered
exactly on the left and right border of the axis.
my Y axis does this just fine (integer data), but my X axis has no
buffer/margin what soever.
my graphing routine is as such (most fields are variables) any help is
appreciated!:
PlotVar.set_xlabel(xlabel)
PlotVar.set_ylabel(ylabel)
PlotVar.set_title(title)
PlotVar.plot(data[xtarget][np.isfinite(data[ytarget1])],
data[ytarget1][np.isfinite(data[ytarget1])], '-o', ms=6, lw=2, alpha=0.5,
mfc='orange', label=label1)
PlotVar.plot(data[xtarget][np.isfinite(data[ytarget2])],
data[ytarget2][np.isfinite(data[ytarget2])], '-o', ms=6, lw=2, alpha=0.5,
mfc='red', label=label2)
PlotVar.xaxis.set_major_locator(xdays)
PlotVar.xaxis.set_major_formatter(DateFormatter('%m-%d'))
PlotVar.xaxis.set_minor_locator(xhours)
PlotVar.fmt_xdata = DateFormatter('%m-%d')
figVar.autofmt_xdate(rotation=-90, ha='left')
highY1 =
max(data[ytarget1][np.isfinite(data[ytarget1])])
lowY1 =
min(data[ytarget1][np.isfinite(data[ytarget1])])
highY2 =
max(data[ytarget2][np.isfinite(data[ytarget2])])
lowY2 =
min(data[ytarget2][np.isfinite(data[ytarget2])])
maxvalue = max(highY1, highY2)
minvalue = min(lowY1, lowY2)
PlotVar.yaxis.set_major_locator(mticker.MultipleLocator(base=round(((maxvalue
- minvalue)/10),3)))
PlotVar.yaxis.set_minor_locator(mticker.MultipleLocator(base=round(((maxvalue
- minvalue)/40),5)))
plt.legend(loc='best',
prop=matplotlib.font_manager.FontProperties(size=10))
PlotVar.grid()
figVar.savefig(saveto)
